First Claim
1. A data receiver for receiving a second image data, the second image data for playing a game on a portable terminal, said second image data comprising image data of a first moving image and digital data encoded as color of part or all of said first moving image, the data receiver including the portable terminal, the portable terminal comprising:
- a light sensing means that senses the light of part or all of a second moving image displayed on a display means, said second moving image including said digital data being encoded as the color of part or all of said second moving image data; and
a digital data decoding means that detects the change in each unit time in the color of part or all of said second moving image sensed by said light sensing means and decodes and generates said digital data;
wherein said light sensing means includes a display assembled into said light sensing means and means for displaying a third moving image thereon; and
wherein said third moving image displayed on said display of said light sensing means is generated based on said digital data that is decoded by said digital data decoding means and said third moving image includes a game character for playing the game based said digital data.

Abstract
According to the present invention, it is possible to, when an already available data communication system is used, transmit digital data other than data that is the main communication object of the data communication system.
A data broadcast station (2)of this invention has a digital data encoder (7), which changes, each unit time, the color of part of a moving image based on digital data that is input and generates image data. A data reception terminal (4) which has a moving image display device (10), which displays a moving image based on image data, a light sensing device (12), which senses the light of part of the moving image displayed on the moving image display device (10), and a digital data decoder (13), which detects the change, each unit time, in the color of part of the moving image whose light is sensed by the light sensing device (12) and generates the digital data.
